I totally agree with J011y. I think it's a great frame, something I've been looking for in while. That said, but it's not for everyone.
IF you are a chronic string breaker, this racket is not for you, but if you're not, this racket will possibly turn you into one. The reason I say that is, I've known a couple of people who have Natural Gut in thier rackets for over two years, and they play at least 2 to 3 times a week.
